Bio 1.2.3 - Explain how specific cell adaptations help cells survive in particular environments (focus on unicellular organisms).
Many organisms develop certain structures over time that help them to survive. Some notable adaptations in unicellular organisms is the presence of contractile vacuoles, cilia, flagella, pseudopods, and eyespots. These organisms also may develop adaptive behaviors that will allow it to carry out processes that will help it to survive in particular environments. Examples of these behaviors include chemotaxis and phototaxis. Below these structures and behaviors are further explained.

- Temporary cytoplasm-filled projections of the cell wall that organisms use for locomotion
- Also used to aid in the gathering of food
